Passenger Conveyor

technical field

The present invention relates to a passenger conveying device including an escalator and a moving walk, and more particularly to a passenger conveying device in which a long non-slip strip is formed on a tread surface in a moving direction.

Background technique

Generally, in a passenger conveying device such as an escalator, as for a step forming a step surface on which passengers stand, the die-casting of an aluminum alloy and the corrugation of a stainless steel plate are described in, for example, Japanese Application Laid-Open No. 2001-89057. On the molded tread surface, tread surface anti-slip strips having parallel, evenly spaced, alternately formed raised portions and slots are installed. In addition, end anti-skid strips made of synthetic resin are installed, which extend beyond either or both of the front and rear ends of the pedal surface in the moving direction in the width direction of the pedal surface. The end anti-slip strips are colored with a noticeable color such as yellow, and use synthetic resin that is more elastic than aluminum and stainless steel.

On the other hand, at both ends of the longitudinal direction of the above-mentioned passenger conveyor, arrival and departure floors for passengers' arrival and departure steps are installed, and a comb is provided at the front end of the arrival and departure floors. The toothed edges of the combs are inserted into the slots of the respective anti-slip strips, and conversely, the tops of the anti-slip strips are inserted into the bottoms of the combs, and the combs and anti-slip strips are mounted to cooperate with each other through a small gap.

In the pedal having the above structure, when foreign matters such as small stones enter the mating portion between the comb and the tread cleat, there arises a problem that the tread cleat is damaged or deformed. The damage and deformation of the pedal surface cleats include the risk of passenger's shoes or fingertips getting into the comb or collision of the pedal surface cleats with the comb, and their recovery requires a lot of time and cost, so this is in A big problem in maintenance that needs a solution to it.

Contents of the invention

The present invention attempts to provide a passenger conveying device capable of reducing damage and deformation of the non-slip strip on the surface of the tread even if foreign matter enters the comb.

According to the present invention, in order to achieve the above object, in a passenger conveying device having a plurality of pedals that are cyclically connected and move cyclically between arrival and departure floors at both ends, the tread surface anti-slip strips have , many raised parts and slots extending along the moving direction, the end anti-slip strip has the same section as that of the pedal surface anti-slip strip and is at the end of the pedal moving direction, and the comb installed at the front end of the arrival and departure floor The shaped part cooperates with many pedal surface cleats and has gaps, and the means for forming a gap smaller than the gap between the pedal surface cleats and the comb is provided on the end cleats.

By using the above structure, when debris enters the comb, the debris comes into contact with the end cleat made of synthetic resin before coming into contact with the pedal surface cleat, so that when the debris passes through the end cleat and the comb When the mating parts between the shaped parts are removed, the sundries are crushed or compressed, and the anti-skid strips on the pedal surface will not be damaged.
